Synonyms: Perfluoro-3-ethylpentane

CAS Number: 2690-05-3

Description & Characteristics

Perfluoro-3-ethylpentane C7F16, is a fully-fluorinated, odourless, colourless liquid with the following characteristics:

  • Compatibility with most construction materials
  • Excellent chemical and thermal stability
  • Non flammability
  • Practically non-toxic1
  • Applications

    Although Perfluoro-3-ethylpentane is predominantly used as a tracer or taggant under the trade name of Perfluoro-3-ethylpentane, it has the same characteristics as other perfluorocarbons and can be used in similar applications.


    Safety, Handling and Storage

    Although Perfluoro-3-ethylpentane is considered biologically and chemically inert, good laboratory practice should be observed when handling.  Perfluoro-3-ethylpentane has an indefinite shelf life if properly stored in its original sealed container.  Safety data sheets are available on request.
